I’ve started playing this game since ver.1.2, also spent all attempts on Irritator in every weekly event contain it.
Also bought all special rare incubators contain it.
(Yes only rare, not buying those epic or premium ones)
My Magna is now lv25, and I do some simple calculation to estimate DNA required for creating hybrids.
I think if I’m really lucky in the following DNA fusion, might be able to reach lv26 at the moment I run out of all Irritator DNA.
So if you used all event attempts on Irritator, but not buy those incubators or speed up arena incubators, I think lv24~25 should be the upper limit of your Magna.
(I don’t think any player will be willing to donate Irritator DNA to others )
